Member Function Documentation

◆ alignment() [1/2]

xtd::drawing::drawing_2d::pen_alignment xtd::drawing::pen::alignment ( ) const
noexcept

Gets the alignment for this xtd::drawing::pen.

Returns
A xtd::drawing::drawing_2d::pen_alignment that represents the alignment for this xtd::drawing::pen.
Remarks
This property determines how the xtd::drawing::pen draws closed curves and polygons. The xtd::drawing_2d::pen_alignment enumeration specifies five values; however, only two values - xtd::drawing_2d::pen_alignment::center and xtd::drawing_2d::pen_alignment::inset - will change the appearance of a drawn line. xtd::drawing_2d::pen_alignment::center is the default value for this property and specifies that the width of the pen is centered on the outline of the curve or polygon. A value of xtd::drawing_2d::pen_alignment::inset for this property specifies that the width of the pen is inside the outline of the curve or polygon. The other three values, xtd::drawing_2d::pen_alignment::right, xtd::drawing_2d::pen_alignment::left, and xtd::drawing_2d::pen_alignment::outset, will result in a pen that is centered.

◆ alignment() [2/2]

xtd::drawing::pen & xtd::drawing::pen::alignment ( xtd::drawing::drawing_2d::pen_alignment  value)

Sets the alignment for this xtd::drawing::pen.

Parameters
valueA xtd::drawing::drawing_2d::pen_alignment that represents the alignment for this xtd::drawing::pen.
Remarks
This property determines how the xtd::drawing::pen draws closed curves and polygons. The xtd::drawing::drawing_2d::pen_alignment enumeration specifies five values; however, only two values - xtd::drawing::drawing_2d::pen_alignment::center and xtd::drawing::drawing_2d::pen_alignment::inset - will change the appearance of a drawn line. xtd::drawing::drawing_2d::pen_alignment::center is the default value for this property and specifies that the width of the pen is centered on the outline of the curve or polygon. A value of xtd::drawing::drawing_2d::pen_alignment::inset for this property specifies that the width of the pen is inside the outline of the curve or polygon. The other three values, xtd::drawing::drawing_2d::pen_alignment::right, xtd::drawing::drawing_2d::pen_alignment::left, and xtd::drawing::drawing_2d::pen_alignment::outset, will result in a pen that is centered.

noexcept

Gets the xtd::drawing::brush that determines attributes of this xtd::drawing::pen.

A Brush that determines attributes of this xtd::drawing::pen.
Remarks
Assigning this property causes the pen to draw filled lines and curves. It overrides thextd::drawing::pen::color property of the xtd::drawing::pen.

template<typename brush_t >
xtd::drawing::pen & xtd::drawing::pen::brush ( const brush_t &  value)
inline

Sets the xtd::drawing::brush that determines attributes of this xtd::drawing::pen.

Parameters
valueA xtd::drawing::brush that determines attributes of this xtd::drawing::pen.

Sets the color of this xtd::drawing::pen.

Parameters
valueA xtd::drawing::color structure that represents the color of this xtd::drawing::pen.
Returns
This current instance.

◆ dash_pattern() [1/2]

std::vector< float > xtd::drawing::pen::dash_pattern ( ) const
noexcept

Gets an array of custom dashes and spaces.

Returns
An array of real numbers that specifies the lengths of alternating dashes and spaces in dashed lines.
Remarks
Assigning a value other than empty to this property will set the xtd::drawing::pen::dash_style property for this xtd::drawing::pen to xtd::drawing:dash_style::custom.
The elements in the dash_pattern array set the length of each dash and space in the dash pattern. The first element sets the length of a dash, the second element sets the length of a space, the third element sets the length of a dash, and so on. Consequently, each element should be a non-zero positive number.
The length of each dash and space in the dash pattern is the product of the element value in the array and the width of the xtd::drawing::pen.

◆ dash_pattern() [2/2]

xtd::drawing::pen & xtd::drawing::pen::dash_pattern ( const std::vector< float > &  value)

Sets an array of custom dashes and spaces.

Parameters
valueAn array of real numbers that specifies the lengths of alternating dashes and spaces in dashed lines.
Remarks
Assigning a value other than empty to this property will set the xtd::drawing::pen::dash_style property for this xtd::drawing::pen to xtd::drawing:dash_style::custom.
The elements in the dash_pattern array set the length of each dash and space in the dash pattern. The first element sets the length of a dash, the second element sets the length of a space, the third element sets the length of a dash, and so on. Consequently, each element should be a non-zero positive number.
The length of each dash and space in the dash pattern is the product of the element value in the array and the width of the xtd::drawing::pen.

◆ dash_style() [1/2]

xtd::drawing::dash_style xtd::drawing::pen::dash_style ( ) const
noexcept

Gets the style used for dashed lines drawn with this xtd::drawing::pen.

Returns
A xtd::drawing::dash_style that represents the style used for dashed lines drawn with this xtd::drawing::pen.
Remarks
A value of xtd::drawing::dash_style::custom for this property specifies that a custom pattern of dashes and spaces, defined by the xtd::drawing::pendash_pattern property, makes up lines drawn with this xtd::drawing::pen. If the value of this property is xtd::drawing::dash_style::custom and the value of the xtd::drawing::pen::dash_pattern property is empty, the pen draws solid lines.
Examples
draw_ellipse.cpp, draw_line.cpp, draw_rectangle.cpp, and draw_rounded_rectangle.cpp.

◆ dash_style() [2/2]

xtd::drawing::pen & xtd::drawing::pen::dash_style ( drawing::dash_style  value)

Returns
A xtd::drawing::drawing_2d::line_join that represents the join style for the ends of two consecutive lines drawn with this xtd::drawing::pen.
Remarks
A line join is the common area that is formed by two lines whose ends meet or overlap. There are three line join styles: miter, bevel, and round. When you specify a line join style for a xtd::drawing::pen object, that join style will be applied to all the connected lines in any xtd::drawing::drawing_2d::graphics_path object drawn using that pen. The following illustration shows the results of the beveled line join example.

Parameters
valueA xtd::drawing::drawing_2d::line_join that represents the join style for the ends of two consecutive lines drawn with this xtd::drawing::pen.
Returns
This current instance.
Remarks
A line join is the common area that is formed by two lines whose ends meet or overlap. There are three line join styles: miter, bevel, and round. When you specify a line join style for a xtd::drawing::pen object, that join style will be applied to all the connected lines in any xtd::drawing::drawing_2d::graphics_path object drawn using that pen. The following illustration shows the results of the beveled line join example.

◆ miter_limit() [1/2]

float xtd::drawing::pen::miter_limit ( ) const
noexcept

Gets the limit of the thickness of the join on a mitered corner.

Returns
The limit of the thickness of the join on a mitered corner.
Remarks
The miter length is the distance from the intersection of the line walls on the inside of the join to the intersection of the line walls outside of the join. The miter length can be large when the angle between two lines is small. The miter limit is the maximum allowed ratio of miter length to stroke width. The default value is 10.0f.
